STAlR-CARPET FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 478,028, dated June 28,1892. Application filed October 8, 1891. Serial No. 408,128. (No model.)

To all whom it may concern:

Be it known that I, THOMAS H. SPURRIER,

a citizen of the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Stair- Oarpet Fasteners and I do hereby declarethe following to be a full, clear, and exact description oftheinvention, such as will enable others skilled in the art to which itappertains to make and use the same. 7

My invention relates to certain improve ments in stair-carpet fasteners;and it consists in the employment of a rod and a peculiarly-shapedfastener and strengthening-cap, and means for securing the same to ariser of a stairway, as will be more fully hereinafter described in thespecification, and specifically set out in the claim.

The objects of the invention are, first, to

prevent the carpet from becoming displaced by elfecting a much greaterbearing-pressure at two or more points; second, to strengthen the rod atthe point where it is weakened by the perforation made to receive thesecuring means; third, to prevent the ends of the rod from springingoutward by effecting an inward pressure upon the rod near the end beyondthe point of fastening, and, fourth, to efiect a bearing between the twopoints of fastening by means of the curved rod. These objects areattained by means of the device illustrated in the accompanyingdrawings,in

. which- Figure 1 represents a front elevation of a portion of astairway, showing my improved device applied for securing the carpetthereon; Fig. 2, a perspective view of the fastener andstrengthening-cap; Fig. 3, a view of the curved or bent rod.

Referring to the drawings, the letter A indicates the step, and B theriser, of a stairway, and C the carpet arranged thereon.

1.) indicates the stair-rod, which may be of any suitable material,half-round in crosssection, and slightly curved or bent longitudinally.The rod is provided a short distance from'its ends with a perforation dto receive a securing-screw F.

G indicates the fastener and strengthening-cap, made of any suitablematerial and ornamented in any desirable manner. It is preferably oblongin shape and concaved to conform to the contour of the stair-rod. It isslightly thicker at the center, where it is countersunk and perforatedto receive the screw F. The saidofastener is made, preferably, about twoinches in length, so that a bearing-pressure will be exerted about aninch on each side of the perforation in the rod.

WVhen the carpet is'in place, the rod is secured to the riser at theangle formed by the step and riser. Owing to the curved or bent featureof the rod, an especial bearing is effected at the center midway betweenthe points of fastening, which tends to hold the carpet against ordinaryefforts of displacement at that point, and prevents the unsightlybagging appearance of the carpet, which is due to the action of the footin ascending and descending the stairs. The fastener, conforming snuglyto the face of the rod, serves the double purpose of strengthening therod at the point weakened by the making of the perforation and producinga greater bearing-surface, not only at the points of fastening to theriser but beyond on each side thereof. The outer end of the saidfastener, extending as it does to within about an inch of the end of therod, also serves to prevent the end of the rod from springing outward,as is often the case where the bearing-pressure is very great. Thisbearing-pressure extends along the entire length of the rod, but is muchgreater at the two ends and the center thereof. The carpet is caused tobe pressed firmly and smoothly against the riserand step, and thereheld. The device is simple and inexpensive to construct and mosteffective in use. It is easily and quickly applied and as readilyremoved when desired.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

The herein-described stair-carpet fastener, comprising a normally-curvedrod, but capable of being bent to lie fiat against the carpet,strengthening-caps conca'ved to conform to the outer face of the rod andarranged at each end of the same, and screws to secure said rod,substantially as specified.

In testimony whereof I affix my signature in the presence of twowitnesses.

THOMAS H. SPURRIER.
